在Spring Boot Services中运行H2数据库多个实例

时间：2019-06-25 09:22:35

标签： java spring-boot microservices h2 multiple-instances

我已经使用嵌入到内存H2数据库中创建了一个Spring Boot应用程序。该应用程序正常运行。在浏览器http://localhost:8080/h2上可以访问我们管理的H2数据库，在localhost:8080/context/service-endpoint上可以访问应用程序服务。这意味着H2数据库和应用程序也可以在同一端口上访问。

现在，我通过传递--server.port=8888来运行Spring Boot应用程序的第二个实例，Spring Boot应用程序在端口8888上启动，但是H2DB无法启动并运行。

在这里，我假设如果在第一个实例中的端口8080上运行，那么在同一应用程序的第二个实例中，具有不同端口的第二个实例也应在指定的不同端口上启动H2 DB，在这种情况下为8888。但是，它失败了。

请帮助。

2 个答案:

答案 0 :(得分：2)

我不是H2专家，但这里的例外情况很好地说明了会发生什么情况。

从您的堆栈跟踪中：

The file is locked: nio:C:/Users/kumar.shorav/test.mv.db

因此，我相信第一个实例将其h2内容存储在此文件中，此过程将其锁定。 现在出现了第二个实例，它可能具有相同的配置集，其中包括在哪里存储文件（在同一位置）。

因此，当它启动时，该文件已被锁定，并且第二个实例的H2无法启动。

现在，这与以下事实无关：您说H2纯粹在内存中运行，至少不是异常所说明的那样

答案 1 :(得分：0)

对我来说，它在停止h2.bat作业后仍然有效。
